which can drive thousands of shimmering RGB LEDs. Then, we did the Sparkle Motion stick, a USB-pluggable version

On the third night, a 1.28" round TFT display

and on the fourth a 1.8" round TFT with captouch overlay

On the fifth night, a tiny 0.85" TFT display

came to life.

This night, we're taking a little bit of a breather since we want to do final testing and hopefully send out the Sparkle Motion PCBs
